The invention discloses a production method for a platinum crystal face wood floor, which comprises the production steps as follows: drying and curing of floor blank, blank processing, primer and paint painting. The invention adopts a vertical-lubrication penetration roller spraying technique, carries out the pre-heating disposal, drying disposal, balance disposal, humidifying treatment, temperature reduction kiln outgoing and curing to the floor blank, then processes the blank and paints the primer; the paint is then coated by adopting eight-bottom and four-surface so as to gain a finished product. The platinum crystal face wood floor prepared by the invention has the advantages that the paint adhesion of the tree with high grease (oil) content is improved; the floor has ultra-strong adhesion from the interior of the wood to the surface; a production process of eight-bottom and four-surface is adopted to combine an elastic, abration and friction resistance environmental protection paint; therefore, the surface filling of the floor is saturated, clear and natural, the chamfers are smoother and the wood floor is more scraping- resistant and wear-resistant; the one-off qualification rate of the product is improved and achieves 99.5 percent, thus improving the quality of the product.

A method for automatically packaging a solar cell piece and a glass covering piece resistant against radiation is used for the solar cell in certain shapes and sizes. The method has the following steps: selecting the inclined packaging angle between the glass covering piece and the solar cell piece through an experiment, programming the moving traces of a packaging unit using a computer, determining the attitude of an absorbing disk which absorbs the glass covering piece, then downloading the documents of the moving traces and the controlling commands into the controller of a robot in orthogonal coordinate of three degrees of freedom so as to meet the specified requirements of the amount and size of the air bubbles using the packaging manner of free-falling body or inclined falling and ensure the relative positions between

The invention relates to a vertical plunger pulverizer. A rotary main shaft of the pulverizer is vertically placed, a pulverizing chamber is divided into a grade-one pulverizing chamber and a grade-two pulverizing chamber that can pulverize soft and hard components of the materials respectively, which is more thoroughly pulverized than the existing technologies, thus reducing the pulverizing times due to re-pulverizing the oversized particles, saving time and improving the production ability of the machine. A hard abrasion resistant materials in an imbedded scaleboard of a shell can further improve the service life and security and stability of the machine; the size of particles can be adjusted according to different requirements; the invention is operated in a negative pressure, which effectively control the overflowing of the nanoids, and beneficial to environmental protection and generate small noise during the process.

A radome for a concave-reflector antenna is fastened directly onto the reflector's edge. The inner surface of the radome comprises at least one absorbent part partially covering its surface area and disposed along its peripheral edge. The surface area of the radome covered by the absorbent part(s) is less than 15% of the total surface area. The radome may comprise two absorbent parts in diametrically opposite positions. Each absorbent part may have a substantially triangular shape, the base of the absorbent part being rounded along the radome's edge, and a portion of its surface area having been removed laterally from each side of the triangle in a circular arc cut-out.

The invention provides a rotary distributor with point-to-point feeding discharging and point-to-point dust absorption. The rotary distributor with point-to-point feeding discharging and point-to-point dust absorption comprises a feeding distribution platform component, a feeding articulated chute component and driving part of the feeding articulated chute component, and a column component used for installing the driving part. A shaft sleeve component is arranged on a main shaft of the driving part on the upper side of the feeding distribution platform. 3-4 umbrella type support bars are stretched from the shaft sleeve component in a sloping downward direction in an equal central angle mode. The lower ends of the support bars are connected with an annular rotating disc which is placed horizontally. The rotating disc is on the feeding distribution platform and matched with the feeding distribution platform gap. The radial width of the annular rotating disc covers a multi-position feeding distribution opening of the feeding distribution platform. A feeding discharging opening of the annular rotating disc is corresponding to a feeding discharging distribution opening of the feeding distribution platform. A lower port of an articulated chute of the feeding articulated chute component is connected with the feeding discharging opening of the annular rotating disc. A dedusting component is connected with the lower end of the main shaft of the driving part. The dedusting component comprises a dedusting component support connected with a flange at the lower end of the main shaft and a dust absorption bending pipe fixed on the dedusting component support. Two ports of the dust absorption bending pipe are respectively corresponding to a bunker dust absorption opening and a system dedusting opening.

The invention discloses a technology for preparing calcium chloride by using waste slurry.
